Json to json Tree Structure

Json to json Tree Structure

When writing a Restful service, because all returned objects are json objects, these objects are related, but they are not well reflected. when returning to the page, cannot be a tree. The returned json string data is as follows:

[{Belongsname:, id: 901, isleaf: 0, name: XJBHX-2 standard Project Department, pid:, type :}, {belongsname:, id: 902, isleaf: 1, name: general Department (office), pid: 901, type: },{ belongsname:, id: 903, isleaf: 1, name: Engineering Department (Technical Department/Technology Department), pid: 901, type :}, {belongsname:, id: 904, isleaf: 1, name: security, pid: 901, type :}, {belongsname:, id: 905, isleaf: 1, name: Financial Department, pid: 901, type: },{ belongsname:, id: 906, isleaf: 1, name: Department of thing (Department of thing), pid: 901, type :}, {belongsname:, id: 907, isleaf: 1, name: Central Laboratory, pid: 901, type:}]

The data we need on the front-end interface may be as follows:

[
{
Belongsname :,
Id: 901,
Isleaf: 0,
Name: XJBHX-2 Project Department,
Pid :,
Type:
Children :[{
Belongsname :,
Id: 902,
Isleaf: 1,
Name: General Department (office ),
Pid: 901,
Type:
},
{
Belongsname :,
Id: 903,
Isleaf: 1,
Name: Engineering Department (Engineering and Technology Department/Technology Department ),
Pid: 901,
Type:
},
{
Belongsname :,
Id: 904,
Isleaf: 1,
Name: Security Department,
Pid: 901,
Type:
},
{
Belongsname :,
Id: 905,
Isleaf: 1,
Name: Ministry of Finance,
Pid: 901,
Type:
},
{
Belongsname :,
Id: 906,
Isleaf: 1,
Name: Department of thing (Department of thing and machine ),
Pid: 901,
Type:
},
{
Belongsname :,
Id: 907,
Isleaf: 1,
Name: Central Laboratory,
Pid: 901,
Type:
}]
]

How to convert it? Example:

 

<%@ page language=java contentType=text/html; charset=ISO-8859-1pageEncoding=ISO-8859-1%>

<Script type = text/javascript> // converts a json string to a function transData (a, idStr, pidStr, chindrenStr) {var r = [], hash = {}, id = idStr, pid = pidStr, children = chindrenStr, I = 0, j = 0, len =. length; for (; I <len; I ++) {hash [a [I] [id] = a [I] ;}for (; j <len; j ++) {var aVal = a [j], hashVP = hash [aVal [pid]; if (hashVP ){! HashVP [children] & (hashVP [children] = []); hashVP [children]. push (aVal);} else {r. push (aVal) ;}} return r ;}// test method function test () {// json string var jsonData = eval ('[{belongsname:, id: 901, isleaf: 0, name: XJBHX-2 standard Project Department, pid:, type: },{ belongsname:, id: 902, isleaf: 1, name: General Department (office), pid: 901, type :}, {belongsname:, id: 903, isleaf: 1, name: Engineering Department (Department of Technology/technology), pid: 901, type :}, {belongsname:, id: 904, isleaf: 1, name: Security Department, pid: 901, type :},{ belongsname:, id: 905, isleaf: 1, name: Ministry of Finance, pid: 901, type :}, {belongsname:, id: 906, isleaf: 1, name: TSL (TSL), pid: 901, type :}, {belongsname:, id: 907, isleaf: 1, name: Central Laboratory, pid: 901, type:}] '); // The bound field var jsonDataTree = transData (jsonData, 'id ', 'pid', 'chinance'); console. log (jsonDataTree);} // method window for loading and executing the form. onload = test; </script>

 

 

Summary:

At the beginning, I thought it was complicated. I thought I would traverse it and manually spell the json string. The network would always do what we did first.
